Fraction of bright point sources identified as stars by Freund et al. (2024). Top and middle panels: Fraction of stars within 200 pc and 500 pc, respectively. The fraction of stars within the solar neighbourhood is asymmetric with respect to the Galactic plane, with fractions as high as 40–70 % along the nearby stellar structures. The dot-dashed white contours indicate the region with the highest concentration of stars within 200 pc (top) and 500 pc (middle) of the Sun. They are derived from the respective smoothed images. Such as the 0.7 keV emission, the profile of the fraction of detected stars within 500 pc of the Sun is skewed towards the south at 220◦ < l < 235◦ and 250◦ < l < 265◦, while it is nearly symmetric at 295◦ < l < 310◦. Bottom panel: Fraction of stars at any distance from the Sun.
